changing the reference design for fmcomms4 on zc706

i am trying to send data from my custom module which generates real and imaginary data on rf fmcomms4 on zc706 using the reference design provided. i have so far been able to build the design and use the no-os driver to see the sine wave on the adc side. now i have my custom module which generates i q data and i want to attach that module to ad9361 without using dac_dma and adc_dma modules provided in the reference deign .my custom module will generate the data and recieve it from adc output pins on ad9361 block.now i have been able to attach my module directly to the ad9361 directly and and have verified the data also.now my problem is that i want to remove the dac_axi and adc_axi dma modules from the design.but every time i do so my output data is changing and i do not get the desired output.is there any changes that need to be made before removing those block .pls help me with this.thank you.

thanks for replying , i was implying that i want to replace the dac ip and adc ip from the reference design and connect my own custom ip directly to send data to ad9361 ip for that what i have done is that i am using util_dac_unpack block in which i am driving my data i and q directly so that i dont have to remove axi_dac block.so i want to know how can i remove those blocks and still be able to send and recieve my data on ad9361 . imean if i comment out the dma init code in api then how do i send my data from the custom ip. and also how do i intialise the ad9361 to send my data from my custom ip what changes do i have to make in code

thanks you it is working now also i have a question i have connected my custom block directly to the input of ad9361 ip block on i0 and q0 so for interfacing my block with that of ad9361 which are the signals that i need for proper synchronisation of data that i want to send on rf
